Of course you could spend a lot of money to attend one of the big named "Improv Mills" that use students to feed the machine, and put that on your resume. But if you really want to learn to improvise, to learn skills to be able to improvise at an audition, then you need to train with someone who cares about you learning.
A.I.S. was founded by Second City Chicago alum Bill Applebaum. Bill, a member of the board of the SAG Conservatory, uses techniques he learned directly from those who started the modern improv movement. He helps people access their unique creativity.
